- The Eredar, who are represented more or less as "classical" demons, started out as good but were corrupted to evil by Sargeras. They are the leaders of the Legion.
- Assorted lesser demons like the Pit Lords, Mo'arg, Gan'arg, Doomguard, etc., form the armies of the Legion.
- The Scourge are the Undead forces under the command of the Lich King. Originally subservient to the Legion, Ner'zhul eventually betrayed Kil'jaeden and became independent.
- The Shadow Council, an Equal-Opportunity Evil group of warlocks originally founded by Orcs on Draenor, works to further the Legion's goals.
- There are enclaves of demons, cultists (mostly influenced by the Shadow Council), and satyrs throughout Azeroth that are aligned with the Burning Legion and eagerly await their return.
open/close all folders
- Authority Equals Asskicking: During the Invasions, the Lords (who appear in Stage four) are more powerful than most bosses you'll encounter, able to kill any player - except maybe tanks - with one backhand slap.
- Always Chaotic Evil: Justified, you have to be evil (or become corrupted) to get into the Legion in the first place.
- Big Red Devil: Red is one of the most common skin colors for man'ari eredar. The other is dark grey.
- Body Backup Drive: Word of God revealed during Warlords of Draenor that the Twisting Nether, to which the souls of all demons are tethered, transcends all realities. This means that every version of a demon, across all realities, is the same person with the same consciousness. Since demons can only die if their soul is destroyed in the Nether, this effectively gives every demon as many Body Backup Drives as there are realities, especially since Warlords of Draenor (and previously Twilight of the Aspects) proved that jumping between realities is a very real possibility. If Archimonde, for example, really wanted to manifest on main universe Azeroth again, he'd just have to find a way to hop one of his alternate reality bodies over.
- The Corruption: How they "recruit" new species; for example, fel orcs and satyrs were once normal orcs and night elves who were mutated by fel power.
- The Dark Side: Fel energy empowers magic users dramatically, at the cost of corrupting their mind and submitting them to the Legion's will. The Light is its complete opposite.
- Demon Lords And Arch Devils: The Legion has a hierarchical structure, which originally had Sargeras in overall command, and Archimonde and Kil'jaeden as his lieutenants. As Archimonde is dead and Sargeras is stuck in the Twisting Nether, Kil'jaeden is now the de facto leader.
- Determinator: No matter how the people of Azeroth keep ruining its invasion schemes, the Legion will keep trying.
- Elite Mooks: Wrathguards, a subtype of man'ari eredar that specializes in melee combat along with some fire magic. They are shock troops and honor guards for the Legion's commanders.
- Evil Is Bigger: Most are at least slightly bigger than your character, and they get bigger as their level of authority and might grow. The Lords are the size of towers.
- Evil Is Hammy: As the provided quotes show, they love to taunt enemies with the hammiest threats imaginable. (Not that the good guys are much better in that regard.)
- Evil Sorcerer: The man'ari eredar, at the top of the Legion power structure, are usually this.
- Fighting a Shadow:
- Sargeras is so powerful that death may not even be a possibility, at least not by anyone other than a fellow Titan, and the most that the heroes of the universe have managed is sealing away his physical form via Portal Cut. This also applies to the Nazrethim, as they can't be slain unless they're on their homeworld or a place saturated in the power of the Twisting Nether. Other demons are implied to share the same immunity, but pit lords and the three Eredar lords (Archimonde being a good example) have shown that they can be permanently slain on other worlds.
- Or not so permanently. All of the Legion's demons are bound to the Twisting Nether, which exists outside of the timelines of titan ordered planets. This means that any demon that has been killed has its essence returned to the Nether where it can reform, though it takes time depending on its power. Sargeras has yet to reform (maybe because of his avatar's body being sealed away), but Archimonde took the time between the Battle of Hyjal (Warcraft 3) and the Iron Horde's invasion (Warlords of Draenor).
- Alternately, if a member of the Legion dies, they may lose the ability to manifest on that planet. Archimonde and Mannoroth have yet to manifest themselves on Azeroth a second time, and Mannoroth had to be re-built and resurrected to return on Past-Draenor. The limits and extent of this ability are not clearly stated. It doesn't help that demons were never stated to have any resistances to death prior to Warlords of Draenor other than being tough to kill in the first place. With the new expansion focusing heavily on the Legion, hopefully we will get some more definitive lore regarding their souls and what it takes to kill them.
- There are a few stated ways to kill demons in uncorrupted worlds. The sword Ashbringer kills demons (and undead) dead, as it is a powerful relic of The Light. The Illidari have also learned to slay demons permanently (presumably by using the fel energies in themselves).
- Golem: Infernals and Abyssals are large constructs made from stone and animated by demonic fire, which the Legion (and warlock players) can summon in the form of fireballs dropping from the sky.
- Hell Hounds: The Legion uses Felhounds, demonic hounds that feed on magic.
- Humongous Mecha: Fel Reavers are gigantic robots running on fel energy. They are the Legion's biggest assault units by far.
- It's Personal: Azeroth is the only planet ever to have fought the Legion off successfully, and they've actually done so multiple times. At this point the motive for demons attacking Azeroth seems to largely be revenge-based and for Sargeras, to prevent Azeroth's world-soul from falling to the Old Gods' corruption. Confirmed by Blizzard to be (at least current timeline Kil'jaeden's) their motivation for attacking Azeroth.
- Legion has also revealed that Sargeras is infatuated with Azeroth's (female) world soul.
- Large and in Charge: The leaders are titanic, towering over their minions and enemies on the battlefield. Commanders are much larger than players too.
- The Legions of Hell: In addition of having nearly the same name, they are army of demonic beings bent on travelling between worlds to destroy and conquer them, corrupting everything on their way.
- Master of Illusion: Legion is playing up their ability to disguise themselves as mortals. In the followup quest to the Broken Shore scenario, the new demon hunter members of the Horde or Alliance will reveal that magically disguised demons have infiltrated the area using their Spectral Sight ability, and battle ensues.
- Mooks: The Mo'arg species of demons generally serve as the rank-and-file of the Legion. The actual race called the Mo'arg almost always serves the Legion in a Mad Scientist capacity (in Legion they have started showing up as front-line Giant Mooks), and the stunted subtype called the gan'arg are minor laborers and technicians. The subtype called Felguards are the Legion's front line troops; occasionally they can be huge.
- Omnicidal Maniacs: Pretty much the whole point of their existence.
- Obviously Evil: Armies of demons who cause Dramatic Thunder via their very presence, spew poison, flames, and necrotic energy, killing everything in sight. Can't get more obvious than that.
- Our Demons Are Different: More specifically, they are an army of diverse creatures from various worlds who use a form of evil magic known as Fel Power and use The Corruption to assimilate new species in their ranks.
- Out of Focus: The Legion were hardly mentioned at all from Wrath of the Lich King through Mists of Pandaria, primarily because there were much more imminent threats to tackle. They got more screen time in Warlords of Draenor (with Archimonde being the final boss, similar to how Kil'jaeden was the final boss of Burning Crusade) and are the primary antagonists in Legion, where they begin their largest incursion on Azeroth to date.
- Retcon: See the entry for Sargeras.
- Ridiculously Fast Construction: During the invasions in the pre-Legion world event, they can deploy towers that are constructed in seconds (Baine Bloodhoof specifically mentions this in the Broken Shore scenario), which can be destroyed by breaking their protective fel crystals. Justified in that the structures are probably pre-built and are being summoned to the battlefield.
- Sickly Green Glow: Fel power seems to emit this, and players will see this coming from their demonic forges and cannons.
- Spikes of Villainy: Man'ari eredar have small spikes surrounding their eyes, which the draenei lack. Also, Felguards have large spikes that seem to grow from the top of their back, just behind the neck.
Sargeras is the Burning One, the master of the Burning Legion. Originally a Titan, he fell from grace and decided to undo all of creation, returning it to the Twisted Nether. To that end, he enlisted the aid of the original Draenei race, promising incredible power to those who would follow him. Sargeras and his Burning Legion moved from world to world, eradicating or corrupting all life thereon, until they were attracted to Azeroth by the wanton use of magic by the Night Elves. They found the planet a tough nut to crack, however, and the Legion tried many ploys ranging from brute force to corruption to infiltration.Eventually, Sargeras attempted subterfuge. He allowed a young and naive Guardian to discover his "plan" to enter the world in physical form. When she attacked and destroyed him, his spirit entered her body and was later passed on to her offspring, Medivh. Under Sargeras' domination, Medivh opened the Dark Portal, allowing the Orcs to enter Azeroth and starting the First War. It was not until the Second War that Medivh's corruption was exposed; his death banished the spirit of Sargeras back to the Twisting Nether. It is not known if he can return.
- Ascended Extra: Originally just a footnote in the Warcraft II manuals.
- Badass Beard: He had a beard before. But now it's made of FIRE!!
- BFS: Depicted wielding a sword as large as he is while still fighting for the titans, and a smaller one with a jagged tip after his corruption. If the Tabletop games are to be believed, they are Gorshalach, the most powerful weapon in the universe, and Gorribal, what's left of Gorshalach after it shattered itself and was reforged. According to Chronicle, it was shattered during the battle with his old comrade Aggramar and remained that way ever since.
- Big Bad: He is personally directing the Burning Legion during the War of the Ancients, and the invasion of Azeroth by the orcish Horde is his doing through the possessed Medivh.
- Demonic Possession: Of Medivh, starting back when he was in the womb.
- Enemy to All Living Things: It's one of his titles and he's said to turn the temperature up by 50 degrees in a thousand mile radius from his location.
- Even Evil Has Loved Ones:
- "Love" might be a bit a a stretch for a genocidal sociopath, but Legion has revealed that he wants the female titan world soul inside Azeroth to belong to him.
- The lore behind the Fangs of the Devourer artifact weapons state that he had a pet felhound named Goremaw that he greatly cared about. When the child of a conquered world killed Goremaw in its sleep, Sargeras was so furious he destroyed the entire planet and its population in one attack.
- Expy: Of Surtur from The Mighty Thor, and by extension Surt from Norse Mythology. Also shares traits with Morgoth (and several of them with Satan, as mentioned below). He may also be inspired by the very similarly named Sargonnas, as both are powerful warriors, and both are presented with a pair of giant horns.
- Face–Heel Turn: Once the Titan's Champion, he wandered the universe fighting, vanquishing and imprisoning demons wherever he could find them while protecting the planets his kind had seeded with life. An encounter with a world corrupted by the Old Gods, including the Titan that slept within, drove him to destroy that planet and try to convince his fellow Titans that they needed to stand against the Void Lords, and when they refused and thought him mad he decided the only way to stop the Void Lords was to purge all creation.
- Fallen Hero: His former title was "Sargeras the Defender", after all. Then he realized the universe he was trying to defend was beyond normal means of saving, in his eyes, and turned to more...radical methods.
- Flaming Hair: He had normal hair before his fall, but after shattering the prison world of Mardum and releasing the demons there his body absorbed the fel power within the planet and turned it into flames.
- Freak Out: Upon learning that there were beings in the universe capable of corrupting world-souls, he separates from the Pantheon, and turns the swarm of demons he once imprisoned into his army to cleanse the universe.
- Greater Scope Villain: Long after he's dropped off the face of the plot, his Burning Legion continues to cause problems on Azeroth.
- Good All Along: A very, very downplayed example, while he isn't nearly by any stretch of imagination good, but it was originally believed Sargeras wanted to destroy the universe for the sole sake of it. Legion reveals his motivation is to stop the Void Lords from bringing everything to nothingness, showing he at least has noble motives, if horrible ways of going through with his plan.
- He Who Fights Monsters: He seeks to eradicate all life in the universe because the Void Lords want to corrupt and dominate all of reality.
- I Did What I Had to Do: When he found a world soul being corrupted by Old Gods, he determined that it was too far gone, and cleaved the planet in two. The Pantheon admonished him for this act, believing that it could've been saved, which led to his Start of Darkness.
- Kill the God: Sargeras killed the rest of the Pantheon when they tried to stop him.
- Last of His Kind: He killed all the other Titans when they tried to stop him. He and the last world soul in Azeroth are the only Titans left.
- Magic Knight: Sargeras was the Pantheon's physical combat specialist, but he has a command of sorcery that is more than substantial.
- Non-Standard Game Over: If Sargeras physically arrives on Azeroth with his full power, we lose. Nothing on Azeroth can stand up to him save perhaps the Titan Azeroth herself.
- Omnicidal Maniac: His personal reason for beginning the Burning Crusade is to destroy everything to prevent the Void Lords from conquering reality.
- Person of Mass Destruction: According to Krasus, Sargeras individually was a much greater threat to Azeroth than the entire rest of the Burning Legion combined.
- Physical God: He is of course a Titan, with all the ambiguity and Flip-Flop of God that apply to them as a whole.
- Portal Cut: The portal being used to summon him to Azeroth through the Well of Eternity closed on him when he was partway through. The force obliterated his physical body. His spirit would not be gotten rid of so easily, though, and he remained scheming even without a permanent body, having to settle for projecting avatars containing only a shadow of his true might.
- Originally, the eredar and nathrezim (dreadlords) were said to have each played a role in corrupting Sargeras into their ranks. The eredar were removed from this equation around the release of the Burning Crusade expansion, instead having Sargeras be the original evil who corrupted the eredar (later called man'ari eredar). This allowed the rest of the eredar (the draenei) to become a separate race and join the Alliance.
- Chronicles volume 1 goes into depth: What corrupted Sargeras was the knowledge that there were Old Gods being hurled through the Great Dark Beyond with the purpose (and power) to corrupt world souls, with the end goal to end existence. The ones to tell Sargeras this was a group of nathrezim who lived on an Old God infested world.
- Satanic Archetype: At least in terms of backstory.
- Stalker with a Crush: One of the Legion lorebooks has revealed that he had a vision of Azeroth's titan world soul shortly after the War of the Ancients in which she opened a single eye at him and instantly knew she had to be his.
- Super Strength: His strength was said to completely dwarf that of one hundred dragons and he could easily cleave a planet in half. Sargeras was nearly strong enough to hold a closing portal open with his bare hands; in perspective, the portal was compared to a black hole in destructive force. That puts his physical strength near Superman at his strongest (when the latter could move planets).
- Unholy Matrimony: He presumably wants this with Azeroth's titan world-soul after he corrupts her.
- Well-Intentioned Extremist: How he views his Start of Darkness. Believing that a universe devoid of life would be better than one controlled by the Void Lords, his purpose is to stop the Void at all cost to prevent to prevent it from overwhelming the Light and return the universe to nothingness.
- Winged Humanoid: Once he becomes evil, as can be seen in the Warcraft Saga comic, published in the World of Warcraft Magazine.
- Woobie, Destroyer of Worlds: He was so traumatized by the realization that the Void Lords were attempting to destroy the universe and nearly did so by corrupting one of his unborn kin with the Old Gods, combined with the rest of the Pantheon's disapproval of his act of Mercy Killing the titan and refusing to listen to him that he decided the only way to save the universe was to purge it with fire and lead an army of the very demons he had worked all his life to contain.
- Xanatos Gambit: Several, but most particularly the one with the Guardian. If she destroyed him, then he can reincarnate. If she failed, one less guardian is still a good deal.
Kil'jaeden the Deceiver
"There are more ways to destroy one's enemy than with an army. Sometimes those ways are better."Currently the leader of the Legion, Kil'jaeden was one of the three original Eredar lords who were approached by Sargeras and one of the two who joined the fallen titan. While his companion, Archimonde, tended to preferred brute force, Kil'jaeden went the Magnificent Bastard route, manipulating, tempting, and even outright lying to accomplish his goals. After Sargeras was banished with the death of Medivh, Kil'jaeden sought to take over leadership of the Burning Legion and prove his worth by completing the assimilation/destruction of Azeroth. Kael'thas attempted to summon him into Azeroth but didn't finish the job, leaving half of Kil'jaeden's body sticking out of the Sunwell. Consequently, he was ultimately defeated (but not killed) at the Sunwell by the combined forces of the Blue Dragonflight and a band of heroes.
- Alphabetical Theme Naming: The three original Eredar "brothers", all have a "D" title (Kil'jaeden the Deceiver, Archimonde the Defiler, and...Velen the Divine). Even though the third brother is good-aligned, his title still starts with a "D".
- Best Served Cold: He wants revenge on Velen, and partially accomplishes it by having let him think he killed his son, only to raise him as one of the most monstrous eredar until Velen himself would be forced to fight him.
- Big Bad: Of The Burning Crusade, though all the advertising was focused on Illidan until the release of the Sunwell.
- Big "NO!": Upon being defeated at the Sunwell.
- The Chessmaster: His focus is on cunning plots and trickery, to balance out Archimonde's brute force.
- The Corrupter: His personal machinations led to the orc clans slaughtering the draenei of Shattrath and drinking demonic blood; turning Ner'zhul into the Lich King; and Kael'thas turning on both Illidan (leading to Illidan's downfall) and his own people (beckoning a new invasion of Azeroth). In Legion, he also takes great interest in bringing the Illidari into the Legion, and it's implied he was responsible for many other races joining the Legion's ranks.
- Co-Dragons: To Sargeras; shared with Archimonde.
- Did You Just Punch Out Cthulhu?: Justified, since he was not completely summoned when players fight him and is fought with only part of his full power.
- Dragon Ascendant: Specifically in that Sargeras, the canonical Big Bad, is defeated before Kil'jaeden; however, this is not a case of the latter slacking so much as the former getting careless.
- Evil Is Petty: Velen notes that it is no coincidence an attack on the draenei ordered by Kil'jaeden is led by an eredar commander as a "creative" punishment. Even more so when said commander is revealed to be Velen's own son, taken and raised by Kil'jaeden for the sole purpose of being used as a weapon against his father.
- Final Boss: Of the Burning Crusade expansion.
- Gambit Roulette: Kil'jaeden has an extremely long-term mind set, so he naturally does nothing but these. Considering he could empower Ner'zhul with, among other things, limited foreknowledge of future events, it's not completely out-there to consider he might have a bit of prophet in himself as well.
- Genre Savvy: Unlike Archimonde, it looks like he has read about half of the Evil Overlord List.
- Hot as Hell: Implied to help in drawing his victims to the dark side.
- It's Personal:
- According to Word of God, Kil'jaeden did his job for the Burning Legion without letting his ego get the better of him and just saw Azeroth as just another world to conquer. Now, after his defeat at the Sunwell? He is pissed.
- He also took Velen's "betrayal" very personally - while Archimonde was not really bothered by it, and encouraged Kil'jaeden to just let it go, and instead focus his attention on destroying and conquering countless worlds for the Legion, Kil'jaeden never stopped searching until he found his "brother" about 25,000 years later at Draenor.
- Man Behind the Man: He was behind Illidan's plans in Frozen Throne, and was secretly behind Kael'thas's plans in Burning Crusade.
- Manipulative Bastard: They don't call him The Deceiver for nothing. His most notable example of deception, and possibly the origin of the epithet itself, is his impersonation of the orcs' ancestral spirits, which allowed him to convince the orcs to attack the draenei. This plan fails in Warlords of Draenor due to the actions of Garrosh Hellscream. As revealed by the Burning Legion Missive, Archimonde's patience with Kil'jaeden's methods has reached its end, and he is ready to simply take Draenor using his preferred method: good old-fashioned brute force.
- Never Found the Body: Kil'jaeden's defeat at the Sunwell technically banishes him back to the Twisting Nether rather than completely destroying him, raising the possibility that he could return.
- Never My Fault: In the "Tomb of Sargeras" audio-drama, Kil'jaeden repeatedly puts the entire blame for the failed Draenor campaign on Gul'dan. While he doesn't respond aloud, Gul'dan recalls doing his part — Gul'dan was The Unfought, it was the Legion that faced adventurers and failed to conquer Draenor while he was opening the Black Gate.
- Red Oni, Blue Oni: Blue to Archimonde's red, despite their coloring. Kil'jaeden is a schemer who doesn't like to waste his forces, while Archimonde always goes for the frontal assault and damn the consequences.
- Satanic Archetype: While Sargeras has the backstory, Kil'jaeden is a better allegory in terms of personality and appearance.
- Sealed Evil in a Can: Technically - it requires the Sunwell to be reopened for Kil'jaeden to attempt physical entry into Azeroth, which Kael'thas is only too happy to provide.
- Winged Humanoid
- A case of Power Gives You Wings, since normal eredar don't have them.
- You Have Failed Me: Averted. He's surprisingly forgiving of his underling's mistakes, as long as they don't completely screw up his over-all plan. In other times, it IS actually part of his plan (he expects them to fail), so no real failure there.
- This is in contrast to his fellow Co-Dragon Archimonde, who is of the "return victoriously or not at all"-type.
Archimonde the Defiler
"Tremble Mortals, and despair! Doom has come to this world!"The Final Boss of Warcraft III, Archimonde the Defiler was the second of the Eredar lords that took Sargeras' offer of power and became one of his most powerful lieutenants. Unlike Kil'jaeden, Archimonde prefers a much more...direct approach to conquering the universe. He takes battles into his own hands instead of sitting back and plotting. Archimonde participated in the War of the Ancients, where he managed to kill Cenarius' father Malorne. Ten thousand years later he was brought back into Azeroth by Kel'Thuzad to lead the Legion's army. He promptly began destroying Lordaeron before crossing the sea to destroy Kalimdor. There he was held off by a coalition of Alliance and Horde members while trying to drain the World Tree Nordrassil of its power, before being blown up by thousands of wisps.In Warlords of Draenor, Archimonde sees that Kil'jaeden's plans to manipulate the orcs have failed and so takes over the invasion of Draenor. Where Kil'jaeden favored deceit, Archimonde is much more brutal. As a result, the demons in the alternate timeline don't bother hiding themselves like they did in the main timeline and are invading Draenor in force.
- Ambiguous Situation: There is some debate as to whether Archimonde is alive or dead after Warlords of Draenor. Since he pulled the players into the Twisting Nether for the last stage of the fight on Mythic difficulty, some argue that he was killed in the Nether and thus finally Killed Off for Real. Others say that, as the ending cinematic shows, he didn't truly die until he was back of Draenor, sparing him for a another Back from the Dead. Word of God only states that the specifics for killing a demon in the Nether are yet unknown, essentially leaving the door open for his return should Blizzard choose to go that route.
- Back from the Dead: Due to the alternate timeline in Warlords of Draenor. The player can obtain a Burning Legion Missive in Talador that contains a message from Archimonde to Kil'jaeden; apparently Archimonde is annoyed at Kil'jaeden's failure to corrupt the orcs via subterfuge in this timeline and is ready for a more, er, direct approach: "The sky will rain fire...the oceans will be filled with blood...DRAENOR WILL BURN!".
- Badass Boast: See the quote at the start.
- Bad Boss: Kills his own men in frustration after Tyrande escapes.
- The Brute: In terms of personality, at least.
- Call Back: Just as his ally Kil'jaeden emerged as the surprise final boss for BC, he sneaks into Warlords as the final boss of Hellfire Citadel. Unsurprisingly, some of his attacks are reminiscent of the Hyjal encounter.
- Co-Dragons: To Sargeras, with Kil'jaeden. Mannoroth and Tichondrius are his Dragons.
- Death of a Thousand Cuts: After ripping through hundreds of mortal forces. Archimonde was finally killed by Wisps, the basic Night-Elf Worker Unit.
- Defeat Equals Explosion: His death emits a wave of flame that incinerates most of the forest on Mount Hyjal and greatly damages the World Tree Nordrassil.
- Did You Just Punch Out Cthulhu?: Subverted, you aren't supposed to kill him in the final mission, and doing so is extremely difficult because not only do his bases never run out of resources and he can build units that can't be built in normal games, Archimonde himself is nearly unstoppable in a head on fight. In the Battle for Mount Hyjal instance, you bring him to 10% HP and then the wisps do the rest. Finally played straight in Warlords of Draenor, where no wisp assistance was needed to take him down.
- Dragon with an Agenda: Wished to steal the power of the World Tree for himself in order to take command of the Burning Legion from Sargeras and Kil'jaedan.
- Evil Sounds Deep: Very evil, and has a very deep voice.
- Fallen Hero: Legion retcons his backstory: In his youth, he banded together with others to overthrow his master and ruler who consorted with dark entities (implied to be the Old Gods) and put his skull on display as a warning. He ended up doing pretty much the same thing when Sargeras showed up.
- Final Boss: Of Warcraft III: Reign of Chaos.
- Also the final boss of the Hyjal Summit raid in The Burning Crusade.
- serves as this in the Hellfire Citadel raid in "Warlords of Draenor."
- Finger Poke of Doom:
- Foe-Tossing Charge: His march to Mount Hyjal was little more than this.
- Foreshadowing: The Burning Legion missive toy in "Warlords of Draenor" features a conversation between Archimonde and Kil'jaeden about the fate of Draenor, illustrating how pissed Archimonde is about the stunt Grommash pulled. Archimonde later becomes very active in doing something about it, throttling the Iron Horde with fel energy through Gul'dan.
- Genius Bruiser: Emphasis on the "Bruiser".
- Greater Scope Villain: He spearheads the Burning Legion's invasion of Draenor through Gul'dan, but he doesn't appear personally. Until the end of Hellfire Citadel, where he is the last boss.
- Hopeless Boss Fight: Subverted in the final mission of Warcraft III. Because it's a Hold the Line mission, the player is not meant to directly face him. But when this is attempted, it cannot even be called a hopeless boss fight, since Archimonde removes any attacking army as if they are flies, and when he actually does attack you, he'll likely show up when there's already an army on your doorstep. Part of the reason for this is because Archimonde is immune to spells and can only be damaged by chaos attacks. The fun is that the player has no units at their disposal that inflict chaos damage except for the units from the Mercenary Camp nearby.
- Hijacked by Ganon: After Gul'dan and Grommash spent the expansion vying for the position of Big Bad, Archimonde, who had already appeared as the Final Boss in a previous raid, takes center stage.
- The Juggernaut: The last level of Warcraft III has Archimonde stomping through the orc, human, and night elf defenses effortlessly.
- Kill 'em All: His plan for Draenor's inhabitants.
- Killed Off for Real: Slain by dozens of wisps all exploding at the same time around the World Tree. Until it was Subverted in Warlords of Draenor, where he comes back. See Body Backup Drive above, Archimonde has as many back up bodies as there are realities, and he could use all of them provided he has a way to move his physical body between dimensions.
- Large and in Charge: He seems to be able to shrink or grow at will.
- Lord British Postulate: This trope is fully in effect. Observe, how to kill Archimonde without using any cheat on Hard difficulty.
- Made of Iron: In Warcraft III he has an absurd amount of health, and divine type armor which means everything except Chaos damage (which you only get access to through mercenaries in that mission) do a single point of damage to him, he's immune to spells, and he has Ankh of Reincarnation which brings him back to life with 500 hp.
- Meaningful Name: Arch is Greek for king and monde is French for world, i.e. "King of the World" (a title traditionally claimed by Satan). By happy coincidence, it also sounds exactly like "arch-repulsive" in French.
- Neck Snap: Performs this on Malorne in the War of the Ancients.
- Nothing Personal: Unlike Kil'Jaeden, he isn't bothered by Velen's betrayal, and encourages him to let it go.
- Person of Mass Destruction: If him casually destroying Dalaran wasn't evidence enough.
- Rasputinian Death: The last thing he expected was getting zerg rushed.
- Red Oni, Blue Oni: Red to Kil'jaeden's blue, despite their coloring. Archie is impulsive, while Kil'jaeden is calculative.
- Significant Anagram: Remove the "i", and you get "Archdemon".
- The Stoic: During the War of the Ancients, Archimonde was said to hold the same stern faced focus throughout the entire conflict, even in his climatic battle with Malorne.
- Summoning Ritual: Gets to Azeroth via one of these, thanks to Kel'Thuzad. It may actually be what led to his ultimate downfall, as wisps' Detonation deals damage to summoned units.
- Super Power Meltdown: What the wisps do to him.
- Villainous Breakdown: Also his Last Words, though only in the Caverns of Time: Battle of Mount Hyjal instance in The Burning Crusade.
- You Have Failed Me:
- Unlike Kil'Jaeden, Archimonde plays this straight. His policy pretty much boils down to "Succeed or die!"
- Alt!Archimonde as well.
Tichondrius the Darkener
"Calm yourself, Prince Arthas. I am Tichondrius. Like Mal'Ganis, I am a dreadlord, but I am not your enemy. In truth, I've come to congratulate you.."Leader of the Dreadlords and one of the top ranking commanders of the Burning Legion.
- Affably Evil: Very polite and soft spoken. You'll never seen him losing his temper, although sometimes he has to get serious when some of his subordinates talk him back.
- The Bus Came Back: While he was killed by Illidan in Warcraft 3, he has been confirmed to return in Legion first appearing in the battle of the Broken Shore.
- Co-Dragons: Along with Mannoroth, to Archimonde.
- Evil Genius: He does very little fight of his own, instead coming up with the plans and informing the Scourge about them.
- Deadpan Snarker: Which leads to Snark-to-Snark Combat with ArthasArthas: I was wondering when you'd show up.
Tichondrius: I am here to ensure that you do your job, little human. Not to do it for you.
- Finger Poke of Doom: Like Archimonde, he also knows the powerful spell Death Finger.
- Hoist by His Own Petard: He owned the Skull of Gul'dan, and used it to corrupt Felwood. Illidan stole the Skull and absorbed its power, making him powerful enough to kill Tichondrius.
- Mr. Exposition: Spends a good chunk of the Undead campaign in Warcraft III explaining things to Arthas.
- Tempting Fate:Tichondrius: Believe me, brother. Neither the Lich King nor his undead lackeys will jeopardize the Legion's return!
- Winged Humanoid: Like all the Dreadlords, he has quite impressive bat-like wings.
Mannoroth the Destructor
"Stupid, pitiful creature. I am the rage in your heart. I am the fury of your thoughts. I alone empowered you to bring chaos to this world, and by the endless void, you shall!"Leader of the Pit Lords, and the one originally responsible for the corruption of the Orcs. He's quite committed to either bringing them back into the service of the Legion, or killing every last one of them.
- Back from the Dead: Gets brought back from the dead in the Hellfire Citadel raid and once restored is a boss fight.
- Badass Boast: A lot, but in the Warlords of Draenor cinematic:Mannoroth: Hehehaha... You would reject this gift? And did you bring these mongrels here just to watch you... die?
- Blade on a Stick: Two blades on a single stick.
- The Corrupter: Responsible of the orcs going evil in the first two games, as well as the corruption of Grom Hellscream and the Warsong clan in the third.
- Cutscene Boss: Pretty cool cutscene, though. Averted by his actual boss fight in the Hellfire Citadel raid.
- Defeat Equals Explosion: His fiery death mortally wounds Grom Hellscream in Reign of Chaos, and would have done the same to Past!Grom in Warlords of Draenor, if not for a diving save by Garrosh.
- Dem Bones: When he first engages the raid in his boss fight, he is but a skeleton. He regains his flesh later on.
- Double Weapon: His weapon is a huge spear with blades on each end.
- Evil Is Burning Hot: Has green flame running along his head and back in a crest or mane.
- Flunky Boss:
- In the Well of Eternity instance, although he arguably starts out as a Dual Boss, since much of the early fight has you facing Varo'then.
- Straighter example in his Hellfire Citadel fight, where infernals and imps will spawn (additional doomguards in Mythic difficulty).
- Genius Bruiser: Though his Ax-Crazy Blood Knight nature makes it so this doesn't show up much in combat, he's eloquent and extremely intelligent.
- Hidden Depths: Believe it or not, despite being portrayed just as a brute elsewhere, he shows himself to be very competent at sorcery in the War of the Ancients trilogy and very intelligent too (though still not nearly as skilled or smart as Archimonde or Kil'Jaeden).
- Hoist by His Own Petard: Killed by the very first orc that drank his blood.
- It's Personal: He took the Orcs' failure to conquer Azeroth and eventual rebellion very personally, and as a result focuses his effort on enslaving them again in Warcraft 3 to "teach them discipline", even though at this point the Scourge pretty much makes them obsolete as an army.
- Kill It with Fire: Explodes in flames when killed, through which he takes down Grom Hellscream with him.
- Killed Off for Real: Slain twice by Grom Hellscream in two different timelines. Third time's the charm when the raid disposes of him before they face off against Archimonde.
- Large Ham: A broad vocabulary and a deep, loud voice add to this effect.
- Magic Knight: While mostly noted for his physical strength, he also has powerful magic at his disposal.
- Meaningful Echo: His death in the Warlords of Draenor cinematic perfectly echoes his death in the main timeline.
- Playing with Fire: His primary magical arsenal involves lots of fire.
- Stealth Hi/Bye: Pulls this on Grom in the Warlords of Draenor cinematic despite his size and appearance.
- Stout Strength: Pit Lords in general have rather hefty upper bodies, with huge strength to match.
- The Unfought: In WC3, despite being the Arc Villain of the Orc Campaign, you never actually fought him. He is killed by Grom in a FMV instead.
- The Worf Effect: One of the most Legion's most powerful fighters, but he's also been used to show off how powerful somebody else is by having them beat him. He gets manhandled by Azshara in the Ancients trilogy, killed in a single hit by Grom in Warcraft 3 (Though Grom could've been boosted by the corruption from Mannoroth's blood; in effect turning Mannoroth's own power against him), while his alternate timeline counterpart is killed again by Grom in a single hit in Warlords of Draenor (Though he did take an Iron Star to the face right before that). Subverted with his boss fight.
- Worthy Opponent: Despite being a nightmarish butcher, he seems willing to regard others as this in Warcraft III. He says to Tichondrius that he would relish a chance to face Cenarius in combat again and actually applauds Thrall's (unsuccessful) attempt to attack him: "A worthy effort, but futile!"
"This land is ours. The Scourge belongs to the Legion!"A Dreadlord left behind by Archimonde in Lordaeron along with Detheroc and Varimathras. Thought to have been killed by Varimathras as proof of loyalty, and later by adventurers who ventured into the Scarlet Bastion. For the most part, he was manipulating the Scarlet Crusade to do his bidding by posing as Grand Crusader Dathrohan. He later completely shed his disguise and turned the remaining Scarlet Crusade members into the Risen.
- Arc Villain: Of the Paladin Campaign in Legion
- Karmic Transformation: He did this to the Scarlet Crusade members in Stratholme and Tyr's Hand.
- Killed Off for Real: After getting killed by adventurers twice, Balnazzar is finally put down for good in Legion when he leads the assault on Netherlight Temple in person. With Netherlight located inside the Twisting Nether itself, this means Balnazzar isn't coming back.
- Manipulative Bastard:
- He's a good enough one that in his disguise as Grand Crusader Dathrohan he's able to give convincing reasons for all the villages he's destroyed in the name of ending the Scourge(namely that the villages couldn't possibly protect themselves and that the only reason they survived was someone else secretly protected them so that they could reach critical mass for Scourge plaguing which is a convincing excuse.)
- Of course in reality the unseen protector AKA Balnazzar himself was merely gathering the people into those "havens" so that he could deprive the Scourge of corpses to reanimate. The fact he came up with that plan and came up with a reasonable excuse to convince those with moral objections to such methods of destroying the Scourge shows that Balnazzar is in fact the sanest of the Scarlet Crusade to the point that he's a villainous Reasonable Authority Figure.
"I've been waiting for you, young prince. I... am Mal'Ganis."Another Dreadlord, and extremely manipulative to boot. He posed at the original leader of the Scourge in order to lure Arthas to Northrend, starting him down the path leading to him becoming the Lich King. However, Ner'zhul allowed Arthas to kill Mal'Ganis. It didn't stick, and Mal'Ganis returned, having copied Balnazzar and posed as a human to seize control of the Scarlet Onslaught. The players defeated him, and he retreated back to his home planet to regroup.
- Arch-Enemy: Mal'ganis did everything he could to establish himself as Arthas' to lure him to Northrend. It bit him in the ass hard when he learned too late that Ner'zhul had no problem letting Arthas have his vengeance.
- Badass Boast: "I am Mal'Ganis! I AM ETERNAL!"
- The Corrupter: Basically did this to Arthas, and later the Scarlet Onslaught.
- The Dragon: Initially indicated he played this role to the Lich King, prior to the reveal of Tichondrius and Arthas's corruption.
- Karmic Death: After all the things he got away with orchestrating in Lordaeron, his death at Arthas' hands can be considered payment for Stratholme alone, never mind arranging for the plaguing of Arthas' homeland.
- Manipulative Bastard: Stands out even among dreadlords, to the point where he's arguably second only to Kil'jaeden himself.
- The Necromancer: His signature ability in Warcraft 3 allowed him to convert humans who ate poisonous food into undead minions, which he could then teleport away to build up his army.
- Oh Crap!: Has this reaction when he realized that Ner'zhul had no problem with Arthas getting his vengeance on him for all the crap he pulled in Lordaeron.
Once the high councilor of Queen Azshara, Xavius was the night elf who first worked to bring the Legion into Azeroth. After he was killed by Malfurion Stormrage, Sargeras returned him to life as the first of the satyrs. To avoid him returning again, Malfurion bound him within a tree that was eventually sunken below the seas in the Sundering. In the depths of the ocean, Xavius was approached by the Old Gods, and given power over the Emerald Dream to twist it into the insidious Nightmare.
- And I Must Scream: He spent some time as an disembodied spirit being tortured by Sargeras and even more time trapped within a tree at the bottom of the ocean. He actually quotes the trope after coming back from the former instance.
- Arch-Enemy: Of Malfurion. Whatever Xavius' form, whatever sinister force is backing him, he will be gunning for Malfurion and making it his personal goal to force the Archdruid to suffer in some form or another.
- Arc Villain: He's the main enemy of the Val'Sharah region and the Emerald Nightmare raid.
- Back from the Dead: Courtesy of Sargeras, leading to...
- Came Back Wrong: As a monstrous satyr rather than a night elf. Though Xavius prefers it this way, really.
- The Corrupter: First turning other night elves into satyrs, then corrupting the Emerald Dream and those associated with it into the Nightmare. Including the likes of Cenarius and Ysera.
- Death Is Cheap: He's suffered three distinct defeats, each of which Malfurion believed he would never return from. Not only has Xavius continued to survive, he's if anything gotten stronger between each appearance.
- The Dragon: First to Azshara, now to N'Zoth.
- Dream Weaver: He uses the power of the Nightmare to, well, give people nightmares.
- Fauns and Satyrs: The first satyr ever created, though he himself was twisted into this form by Sargeras, and then he started turning other night elves into them.
- Fighting a Shadow: The boss battle against him in Darkheart Thicket is a case of this. The boss is even called the Shade of Xavius.
- Justified, as it is said he cannot use his full power outside the Emerald Nightmare.
- I Shall Taunt You: He does this frequently appears in a shadow form during the Val'sharah quest chain to ridicule your efforts or mockingly inform you of what lies ahead. He usually concludes each encounter with an Evil Laugh while he disappears.
- Red and Black and Evil All Over: His satyr form now looks like this.
- Red Baron: Nightmare Lord.
- Sadistic Choice: Xavius forces Tyrande to make one by choosing between trying to rescue Furion and protecting a temple of Elune from a corrupted Ysera; her husband or her goddess. Tyrande chooses to protect the temple then sends the player character to Darkheart Thicket to rescue Furion.
- The Starscream: As of Legion he's back to working for the Burning Legion, but only to use them against the heroes of Azeroth for the sake of his real masters.
- Transflormation: Was turned into a tree by Malfurion during their second fight. This backfired as it connected him to the Emerald Nightmare and the Old Gods.
- You Are Too Late: A recurring part of trying to stop him in Val'Sharah. Before the player even arrives he's already inflicted Nightmare corruption on Cenarius. When the player tries to gather the archdruids to free Cenarius, they find Xavius has already corrupted one of them too. As a plan B they are sent to retrieve the Tears of Elune, only Xavius has already stolen them.
